SELF-CLOSING VALVE.

To all whom it may concern:

Be it known that I, Wmrmnn S. LIvEN- G001), a citizen of the United States, residing at Kansas Gity,'in the county of Jackson and State of-Missouri, have invented certain new and useful Improvements in Self-Closing Valves; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to: the letters and figures of reference marked thereon, which form a part of this specification. 1

This invention relates to self-closing faucets for use on tanks or containers, and particularly for that class of-receptacles con- 'taining oils and the like.

One of the objects of the invention is to rovide a, self-closing faucet which will be inexpensive to manufacture, which will insure ease of operation, and which, may be so constructed that it.may be temporarily locked against unauthorized use, one of the features being the provision of means for utilizing part of the locking means to assist in maintaining the valve open when it is de sired to empty or partly empty the receptacle to which the faucet is attached.

It is also an object of this invention to provide a means whereby leaka e through the faucet will be revented, .an to this end I have eliminate the necessity for disposing the stufiing box above the-valve seat so that the liability of leakage, due to pressure, will be avoided. I have also simplified the construction of the device and provided means whereby the valve can beunseated by a lever which can be readily inserted into osition and removed therefrom as the occasion may demand. 4

Other objects and advantages of the invention will appear hereinafter, it being understood that changes "in form, proportion, andother minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

Specification of Letters Patent. Patented S t- 23, 1919.

Application filed February 17, 1919. Serial No. 277,480.

Fig. II is a detailed perspective view of the operating lever.

Fi III 1s .a vertical longitudinal sectiona view through a faucet constructed in accordance with my invention, showing the Referring now to the drawings by numerals of reference,

1 designates the valve case which consists of substantially a T-shaped hollow casting, having a threaded inlet portion 2 whereby the faucet may be screwed to a pipe or threaded projection on a tank, the casting being provided with a downwardly projecting nozzle 3, having an outstanding bucket supporting lug 4, and a terminally threadedhose receiving end 5. The end 5 is adapted to be closed by a cap 6, which may be'provided with a fibrous facing 7 if desired, so that in the event that it is desired to' close off the faucet through means of the cap (for example should anything happen to the valve mechanism) this ma be easily accomplished. The casting is a so provided with a polygonal portion 8 whereby the same may be screwed upon a support or pipe by an ordinary wrench.

Within the casting 1 is a valve seat 9, surrounding an opening 10, concentric with the inneropening 2, and alining' with an opening 11, in which is slidably secured 'a valve actuating head or slide'12, the member 12 being also slidable in the box 13, threaded at 14 into the casting 1, and bearing against the packing 15, about the opening 11, whereby a stufling box is provided. The slide 12 is formed with a recess 16 in which one end of the coil spring 17 is seated, the opposite" end of the coil spring bearing against the sleeve 20 is a valve disk 23, one end of which bears against the flange 24 of the sleeve '20,

' the disk 23 being held in lace by a removable sleeve nut 24 threa ed on the end of the, sleeve 20. Since the spring 17 1s an expansion spring, it is obvious that there Wlll be a tendency to move the 'slide 12 away from the guide 18 and thereby seat the valve 23, and this tendency will be augmented by the pressure of oil passing through the mlet 2. y I The box member 13 which constitutes the removable end of the casting 1 is provided with outstanding flanges 25 and'26, spaced apart to bound the lever receiving slot 27,

adjacent to the pocket or slot 27 in slide 12, and these flanges and 26 are provided with slightly curved transverse slots 29 and 30 to receive the oppositely disposed lugs or projections 31 and 32 on the valve operat ng lever 33, said lever having a slot engaglng terminal 34 which is adapted to lie within the slot 28 of the slide 12, as best shown in ber 13, so that when the two openings are in register, the sealing member may be locked insealing position by a padlock 41, or other i i italilr; fastening device, as best shown in 1g. When it is desired to operate the valve, the fastening device .41 must first be removed to permit sealing device 37 to be swung away from the flanges 25. and 26, so

that the operating tool or lever 33 may be put into operating position as best shown in Fig. 3. The lugs or projections 31 and 32 in slots 29 and 30 will act as fulcrums for the lever 33, so that by moving the handle of the lever from right tolleft, the slide 12 will be moved against the spring, and since the valve'23 is rigid on the stem 19, the valve will be unseated. As the lever is movable from right to left the edge 36 of the sealing device 37. may be dropped into one of the notches between the teeth 35, and thereby hold the valve open so that a continuous stream may flow from the tank through the outlet nozzle 5 without attention'of the operator. It will also be noticed that the sealingdevice serves as a means for holding the lever in any adjusted position within the limits of its amplitude of movement.

When it is desired to ermit the valve to seat, the sealing device 3 may be moved out of engagement with the notch portion 35 of 2. A faucet comprisin acasing The lever 33 and its connection with the flanges 25 and 26 and slide 12 is such that a movement can be imparted to the slide by means of the lever in either. direction. This is an advantage in that sometimes the valve mechanism has a tendency to stick so that the valve remains open when such open position is not desirable. If it is necessary to forcibly close the valve or to assist the spring 19, the lever can be moved from left to right, as will be clearly apparent by referring to Fig. III.

From the foregoing description it will be seen that the casing is substantiallya single casting that can be cheaply made, and that the parts may be easily assembled, particularly the slide and its coiiperating. mechanism. After the parts are in place, liability of leakage will be prevented because there are no stuffing boxes or other openings on the pressure side of the valve 23. It will also be apparent that when it is desired to operate the valve and the sealing member 37 is moved out of engagement with flanges 25 and 26, that the lever can be quickly. inserted without any special knowledge of the operating mechanism, and in the event that the lever becomes lost, the valve can be 0perated by placing a nail crosswise in slots 29 and 30 and inserting screw driver or other bar to engage in slot 28 in slide 12.

The device is susceptible of various changes but I have illustrated what appears to me to be the very best form to accomplish the desired result, although I do not desire to be limited to the exact details shown. I f

Having thus described my invention, what I claim as new therein, and desire to secure by Letters-Patent is;
